Abstract: The Beijing new airport terminal and passenger transfer center project is located at Daxing District, Beijing, close to the city of Langfang in Hebei Province.The core area of construction project is over 600 thousand square meters.After completion, the Beijing new airport, together with existing Capital Airport in Beijing, Tianjin Binhai Airport and Shijiazhuang Zhengding airport, will form the Airport Group of Beijing-Tianjin-Hebei Area, to accelerate the Beijing-Tianjin-Hebei traffic integration.It is a national key construction project.The project faces many challenges including the oversized combined structure, large-span steel bridge, complex nodes of vibration isolation system, various forms of steel structure support, curved shape of roof steel grid and complex electro-mechanical system, as well as numerous project participants and difficult construction management.So, the application of BIM technology, focuses on the integration of BIM technology with construction technology, information technology and project management to find scientific and efficient solution to the project construction problems and to promote the management efficiency, which leads this project to a typical case of using BIM technology for smart building.
